Role Overview As Cresta’s Growth Engineer, you’ll build the technical surface of how Cresta goes to market. You’ll develop custom AI agents on Cresta’s own platform for marketing use cases, build the interactive experiences and tooling our growth team runs on, and own cresta.com. This position requires strong engineering fundamentals, high agency, and the ability to go deep in an unfamiliar domain quickly. If you are self-driven, AI-native, and eager to own something end to end, this role is for you. Responsibilities AI Agent Creation • Develop, configure, deploy, and optimize AI agents on Cresta’s platform for marketing use cases, working alongside our forward deployed engineering team. • Build the agent experiences prospects actually touch — event registration, demo and trial surfaces, and the moments where someone would rather just ask Cresta a question. • Take agents from prototype to production, including the evaluation criteria, guardrails, and human review steps prospect-facing work requires. • Integrate agents with the systems behind them — CRM, marketing automation, event tooling — so a conversation produces a real downstream action. • Provide a tight feedback loop to our product and engineering teams: identifying gaps, building custom tooling, and influencing the roadmap through what you learn deploying against a real audience. Growth Experimentation and Tooling • Build the surfaces that don’t exist yet: launch microsites, event experiences, embeddable tools. When a campaign needs something the website can’t carry, you build it. • Build interactive assets that show what Cresta does instead of describing it: calculators, benchmarks, assessments, and demo experiences built on our own product. The Website • Own how cresta.com is built and maintained on Webflow, including the custom code and tooling layered on top, partnering with the agency that handles a portion of day-to-day build work. • Ship the pages, campaign surfaces, and interactive experiences the marketing calendar depends on, working from creative direction set by brand and design. • Own the instrumentation where the site meets our GTM stack, in partnership with Marketing Ops: forms, gated content, event tracking, and attribution. • Ship the technical work behind our SEO and AEO programs, in partnership with the owners of those programs. What We’re Looking For • 7+ years working in software development, web development, AI/ML engineering, or growth engineering. • Strong across the stack — application code, APIs, data, and infrastructure — in Python, TypeScript, Node, or similar. • Familiarity with AI/ML concepts. Hands-on experience with large language models (LLMs), and prompt engineering techniques are strongly preferred. • A track record of learning a domain fast and going deep. You’ve been dropped into something unfamiliar and become the person other people come to. • High agency. You define your own work, ship without being told what to build, and treat gaps as yours to close. • Strong understanding of general AI agent frameworks, function calling, and retrieval-augmented generation (RAG). • Comfortable as the deepest technical voice on a non-engineering team, scoping ambiguous requests and explaining tradeoffs to marketers. • Ownership. You treat the outcome as yours, including when something breaks or was built badly before you arrived. Nice To Have • Experience owning a marketing website. Useful context, not a hard requirement. • Technical SEO and AEO experience grounded in tests rather than theory. • Marketing and GTM systems integration: HubSpot, Salesforce, Marketo, Segment, GA4, GTM.
